Corizoneura leucopicta, Bigot, Mem. Soc. Zool. de Franco, v. p. Glo 

 (1892). 



From Megnin's description there is little doubt that Bigot 

 described the same species. His type (female) and two 

 otlier females, all from New Caledonia, are in a very dirty 

 condition. 



A robust black species. Abdomen with median white 

 spots, halfmoon-shaped, on most of the segments, and others 

 at the sides. Wings dark brown, with the first posterior 

 cell a little narrowed at border. Eyes apparently bare. 

 Palpi black, slender. Antenna black. Forehead protube- 

 rant, a little wider anteriorly. Legs blackish. 



Length 15 mm. ; proboscis 4 mm. 



The name leucopicta appears crossed through, and melano- 

 leuca? substituted, on the label.
